"Let's do something more dramatic. Jon, I think you should be even more of a girl. If I win, your head, face, and neck will turn into a beautiful female version of yourself, so that even your voice changes."
"Fine," Jon said, rolling his eyes. "And if you lose you get to go bald."
Zoe flipped the coin, Jon called heads, and it landed on tails.
"DRAT," yelled Jon. He could feel his face change, but didn't know what it now looked like. He walked over to the hallway mirror. He knew to expect someone different, but he didn't expect such a dramatic change!
His lips had puffed out and his eyes were wider. His eyebrows were plucked and his nose was smaller. He did see aspects of his former face, but this face was much more feminine and beautiful than his.
"Wow," he said, and cleared his throat. He forgot his voice would change as well. Definitely nothing like his male voice before. "Okay Zoe, that was a good one. Now it's my turn for some revenge!"
"Good luck, sis," his sister teased. "I'm gonna have you looking like a California beach blonde within 10 minutes if this keeps up!"
"You wish," Jon said, picking up the coin. "Let's see how you like it with three boobs!"
"And if I win you'll have two of your own at size D!"
Jon flipped the coin. Zoe called tails. It landed heads.
"Drat!" Zoe said this time. "Ow!" Zoe quickly removed her shirt and bra. Just in time too, as a third breast, identical to her other two sprouted up in the middle of her chest. It grew up like a balloon and settled as if it had been there all her life.
Jon couldn't stop laughing. Zoe was laughing too, playing with her new asset.
"You're gonna get it now Jon!" Zoe said, grabbing the coin. "If I win..."
